Thank you very much for your design videos. They are well-detailed at every step. Looking forward to your future uploads! JazakaAllah kheyr.

@mastermindtechnologist2829 4 года назад

Your videos are educative. Please I request for the design of the following structural elements in the cases of compression reinforcement and tensile reinforcement using BS 8110 1) 3 Going staircases and circular staircases 2 Circular column and rectangular columns 3) Cantilever beams and slabs 4) Combined Footings 5) Design of the roof And also how in the cases of earthquake zones, seismic loads and wind loads using British Standard, BS 8110 ( Including the checks)

@mastermindtechnologist2829 4 года назад

And also circular slabs and polygon slabs

@MrElgamal77 4 года назад

Thank you. I have some other videos about beams, slabs and columns in my channel. I will add othe videos in the coming prriod. Thanks.

Hi Dr. S. El-gamal i was hoping that you make a lecture about flat slab and ribbed slab.. I really enjoyed your lecture in design and I hope that you could continue this on useful lectures

that As in the checking for shear represents ?? it is the Asprov but for what ?

@baahzheey8335 2 месяца назад

Hello what if the ly and lx are both 6m and the slab has 9 panels like this do we still use one short end discontinuous for p2?

@MrElgamal77 2 месяца назад

You can do that or you can use one long edge discontinuous. Both will give almost same thing because Ly/Lx = 1.

@davidcivil1651 Год назад

Big thumb up! Just a quick question, can you use the yield line method for using moment etc?

@Bobby14221234 Год назад

Dr are the long span calculated as 6m or 7.2m? Wouldn’t that Bsy now? Thanks very much Dr. El-Gamal.

@chongchen 2 года назад

Hi, I would like to ask that how to calculate the maximum load of the fully clamped two-way RC slab under point load acting on the slab center? I search many design codes and feel quite confusing. Looking for your kind answer.

@martinmtotera282 10 месяцев назад

The simpler way is to convert it to equivalent UDL and add it to the design load

@paulmwangi5061 4 года назад

Hi doctor sherif,we have been waiting for your tutorials,for 2 month you haven't uploaded something.

@hansonhenry5568 2 года назад

Sir what value will you choose for bending moment coefficient for continuous slab if Ly/ Lx is 1.87

@MrElgamal77 2 года назад

From table 3.24 in the BS8110. It differs based on the four edge conditions of the slab.

@raythern6720 4 года назад

Hi, I would like to ask about the effective depth. You calculated the minimum effective depth to be 178mm but after you calculated the total slab depth you reduced the effective depth of the slab to 175mm. Is this correct? because the minimum should have been 178mm and you went for a lower depth

@ahmedalaamri5060 3 года назад

It should have been gone the other way around. h to be taken as 205 mm and effective depth to be taken as 180 mm. The tutor here took literally the solution of the book, maybe he does want to confuse the students when they will refer to the book. All the best

@Bluesky_construct2567 11 месяцев назад

Thanks Dr. for instilling the confidence of design in us. In the case of Ly/Lx not exactly to what is presented in the table, can one round up or interpolate? Your response will be highly appreciated.

@MrElgamal77 11 месяцев назад

Interpolation is the best

@aqoon114 3 года назад

Asalamu alaykum Dr. Sherif. I am student and I would like to ask you to make two-way Rcc slab using Euro code please thanks

@adrimanu1 2 года назад

I prefer BS8110 method for designing 2 way slabs, my question is how would you check if the steel area provided is not above the maximum amount.

@MrElgamal77 2 года назад

Compare it against the maximum 4%. In slabs, you will never go to the maximum. In beams and columns, you may have that.

@mohamedsharawi2020 4 года назад

Thanks for this video,a very clear step by step explanation . I have a question : if the middle panels are 2.5 m width instead of 6.00 m giving one way slab 2.5*7.20 m panels, the case which we find in practice where there is corridor in the building . How can we design the floor slab.

@MrElgamal77 4 года назад

Thank you for you interest. If you have continuous one way slabs with different span lengths where you can not use the coefficients, you have to make the structural analysis using moment distribution method or any simple computer program such as "CBA continuous beam analysis". You can download it from the internet.

@mohamedsharawi2020 4 года назад

@@MrElgamal77 What i mean if we have one way slab adjacent to two (two way slab) from both side .

@MrElgamal77 4 года назад

@@mohamedsharawi2020 Ok. Now I got it. In this case, the negative moment and corresponding top reinforcement can be calculated from the two way slabs. For to bottom steel in the one way slab, you can be conservative and assume it as simply supported and the moment in this case can be wl2/8. Or you can assume the one way slab is fixed from the edges and get the positive moment based on that. I prefere to be conservative and use the first option especially the span is very small and you may need reinforcement less than the minimum.

@mohamedsharawi2020 4 года назад

@@MrElgamal77 But this will not comply with the conditions in clause 3.53.5 (b) which states when using Table 3.14 to calculate moments span of adjacent panels should be approx the same.

@mohamedsharawi2020 4 года назад

My question is : if we have a floor slab with unequal spans say in the Y direction can we use Table 3.14 to calculate moments .
